About this program:



A 6 weeks program liaising experimental and theoretical aspects of Astroparticle Physics will be held at Institut Pascal in Orsay. This program is a continuation of the Paris-Saclay AstroParticle Symposium of 2019 on theoretical Astroparticle Physics. 



Specialist meeting in Astroparticle Physics

  • From High-Energy cosmic rays, gamma-rays, neutrinos to dark matter and gravitational waves.
  • Emphasis on multi-wavelength & multi-messenger studies.
  • Put into context and perspective the revolutionary breakthroughs that occurred in the last few years.
  • Mixed audiences between theorists and experimentalists during most of the programme.


Schedule of topics that will be covered


Week 1: Ecosystem of the Galactic Cosmic-Rays


  • Cosmic Ray acceleration and sources.
  • Propagation and anisotropies.
  • Cosmic Ray composition.


Week 2: Ultra-High Energy Cosmic Rays


  • Anisotropies across all energies.
  • Galactic/extra-Galactic transition.
  • Lessons from neutrinos.


Week 3: Dark Matter Theories


  • Particle Physics scenarios (WIMPS…).
  • Alternatives (Black Holes…).
  • Observable effects (direct or indirect).


Week 4: Dark matter, experiments meet theories


  • The experimental status of dark matter-vs-dark matter theories.
  • Search for exotic phenomena (link to Gravitational waves..).
  • Link with early Universe observations and theories (reheating…).


Week 5: Gravitational waves and compact objects: experiments meet theories


  • Galactic sources of gravitational waves (pulsars, binary systems…).
  • Exotic phenomena (Gamma-Ray Bursts, Fast-Ray Burst…).
  • Multi-messenger astrophysics.


Week 6: Gravitational waves, the theoretical point of view


  • Gravitational Waves: General Relativity meets Quantum Field theory.
  • Black Holes, neutron stars… new physics?
  • Gravitational waves and cosmology.


Further details about this event will follow in the coming weeks.
